FOLDING ORGAN.

Application. med December 3, 1924. seriai No. 753,578.

This invention relates to folding organs and more particularly to thekind in which the stand and mechanism for operating the bellowsareadapted to be unfolded from the 6 organ and placed in position foroperation,

and has for its object the provision of a compact, simple, and easilyoperated organ which may be quickly unfolded into operating position orfolded into position for carrying. It is a further important object ofthis invention to provide a device o`f this kind which has a maximum ofrigidity with a minimum of parts.

lVith the above and other objects in view as will be apparent, thisinvention consists in the construction, combination and arrangement ofparts all as hereinafter more fully described, claimed and illustratedin the accompanying drawing.

On the drawings: y

Figure 1 is a perspective view showing the organ in unfolded positionready for operation. y

Figure 2 is a perspective view showing the organ in folded positionready for being moved about.

Figure 3 is a perspective View showing vthe supporting stand in unfoldedposition before the bellows operating mechanism has 30 been unfoldedinto position.

Figure 4 is a cross-section of Figure 2 showing the parts inY foldedposition.

Figure 5 is a detail View ofthe catch for securing the engagementbetween the sides of the stand and a longitudinal member thereof. y

Figure 6 is a detail view showing the catch for holding the bellows intofolded posit-ion.

As shown on the drawings:

Numeral 1 represents an organ case, which has a cover 2 adapted to beturned back as shown in Figure 1 to permit operation of the organ andthe emission of the sound therefrom. A usual organ mechanism iscontained in the case- 1 adapted to produce musical notes in the usualmanner. The bellows is similar to that shown in my prior Patent No.1,152,475. of September 7th, 1915. A frame t of the bellows is secured`beneath the organ mechanism in the case 1 and is hinged to swingdownwardly at the rear edge of said bellows. The bellows comprises thepumping members 5 and 6 which are hinged to swing downwardly from theforward end of the 'frame 4 and are provided with springs for normallyholding said members upwardly against the frame 4. 'A downwardlydepending catch 7 as shown in Figure 6 is provided in the casing 1 andis-adapted to be operated from the outf side thereof for catchingtheframe 4t of the bellows and holding it in folded position in saidcasing. Hinged within the bottom of the case 1 beneath the bellows is alongitudinal member 8 which is adapted to open downwardly along the rearedge of said bottom as shown in Figure 3. Also hinged within the bottomof the case 1 beneath the bellows are transverse stand members 9 and 10which are adapted 'to open jd-ownwardly along the sideedges of saidbottom and when folded are adapt-ed 'to fold over Vthe longitudinalmember 8 inthe case 1. The longitudinal member '8 is vadapted when swungdownward as shown in said Figure 3 tok tit between the stand members 9and 10 and hold the latter outwardly. Suitable catch members areprovided at the lower corners of thel member 8 which are adapted toengage with adjacent lcatch members on the side members 9 and 10 forholding said members from going beyond `t-he vertical position and formaking the stand more rigid.

Hinged at the lower edge of longitudinal Vmember 8 as shown vin Figure 3is a frame member 11 which is adapted to swing downwardly along saidedge into the position shown in Figure 1. Depending flanges 12 (Figure5) similar tothe catch members referred to on the longitudinal member 8are provided at the forward outer corners of the frame 11 for engagementwith staple members 13 on sides '9 and 10, similar to the aforementionedcatch members on said sides for securing said frame 11 to said sides 9and 10. Hinged on the forward edge of frame 11 as shown in Figure 1 arepedals 14 which are connected to the pump members 5 and 6 of the bellowsby means of straps 15 and are adapted to actuate said bellows.

In preparing the organ for transportation the frame 4.- of the bellowsis moved upward from the position shown in Figure 1 to the f positionshown in Figure 3 and caught by the catch 7. The frame 11 is then foldedupwardly from the position shown in said Figure 1 to the position shownin Figure 3. The cover 2 is closed and secured. The longitudinal member8 is folded into the casing 1 and the stand members 10 and 9 respec- Ciltively are folded thereover and caught by a catch 16.

It will be seen that a compact folding organ is provided in which aminimum of parts are used for a maximum amount of ruggedness andrigidity.

It will also be evident that the `organ is simple and sure of operation.

am aware that many changes may be made, and numerous details ofconstruction may be varied through a wide range without departing fromthe principles Vof this invention, and I therefore do not purposelimiting the patent granted hereon, otherwise than necessitated by theprior art.

I Claim as my invention l. A folding organ, comprising` a ease, abellows therein, leg members hinged in overlapping relation within saidcase and`adapted to be swung .downwardly from the sides thereof, asupporting member also hinged to said case and adapted to be swungdownwardly from the rear thereof, said support: ing member beingConnected to, and bracing said leg members in the open position, andforming a Cover for said leg members in 'the folded position, a framemember adapted to be unfolded forwardly from said supporting member, andpedal members hinged to said frame member and adapted to actuate saidbellows.

2. A folding organ, comprising a case, a bellows therein, leg membershinged in overlapping relation within said ease and adapted to be swungdownwardly from the sides thereof, a supporting` member also hinged tosaid ease and adapted to be swung downwardly from Athe rear thereof,said supporting member being connected to, and bracing said leg membersin the open position, and forming a Cover for said leg members in thefolded position, a frame member adapted vto be unfolded forwardly from.said supporting member, Catch members on said frame member to engagethe forward portions of the leg members in the open posi* tion, andpedal members hinged to the front of said frame member and adapted toaetureeaeee ate said bellows, all of said members being adapted to befolded into said ease for transportation.

8. A folding organ, comprising a ease, a bellows therein, leg panelshinged in overlapping relation within said ease and ladapted to be swungdownwardly fronrthe sides thereof, a supporting member also hinged tosaid oase and adapted to be swung downwardly from the rear thereof forbracing said leg panels, eateh members on said supporting member forengaging the rear portions of said leg panels, a frame member adapted tobe unfolded forwardly from said supporting member, eateh members onsaidv frame member for engaging the forward portions of said leg panels,and pedal members hinged to the front of said frame member and adaptedto actuate said bellows,^'the said supporting member forming a' closurefor said ease and a cover for said leg panels when the organ is foldedfoi` transportation.

ln A folding organ comprising a ease,'a bellows therein, flat leg panelshinged in overlapping relation within the opposite ends of the ease, andswingable downwardly and laterally in the open position, va ease bottomclosure panel overlying lthe leg panels in the folded position andswingable downwardly and rearwardly, means `con-- neeting the `sides ofthe said closure panel in the open position to the rear edges of the legpanels whereby to brace the latter, a pedal frame hinged to the freeedge of the said closure panel Vfor disposition flatwise against theinner face thereofA in the folded position, and swingable downwardly andforwardly therefrom inthe openl position, means connecting the forwardVside portions of said pedal frame to the lower forward edges of the legpanels, and pedals hingedly supported on said frame and having flexibleconnections with the bellows.

In testimony whereof l l'iaveihereunto subscribed my name.
